Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a mobile disassembly tooling. Background Art

[0002] The pump shaft is installed on the pump body through a coupling. When the pump shaft needs to be disassembled, the coupling is reinforced and limited by a disassembly tool, and then a force is applied to the coupling to control the separation between the coupling and the pump shaft. The coupling can be disassembled more labor-savingly through the tool.

[0003] To this end, a coupling disassembly tool with a patent publication number of CN219925906U discloses a coupling disassembly tool, including: a bracket, universal wheels are fixedly installed on the four sides of the bottom of the bracket, a hydraulic column is fixedly installed on the top of the bracket, the inner wall of the hydraulic column is rotatably connected to a support block, and the inner wall of the hydraulic column is movably connected to a threaded column. This coupling disassembly tool drives the bidirectional screw to rotate through a motor, drives the third fixed block and the limit block to move through the first hydraulic rod on the second fixed block, thereby driving the hook to move, thereby limiting and fixing the coupling, and the coupling can be disassembled through the second hydraulic rod on the fixed frame, and a rubber block is fixed on the top of the second hydraulic rod to protect the contact surface when the coupling is disassembled. The setting of this structure can effectively limit, fix and protect the coupling, thereby solving the problem that the bolt hole at the center of the shaft is easily damaged and the outer circle of the coupling is easily deformed.

[0004] When disassembling the pump coupling, since the coupling of some equipment is too large, the ordinary clamping structure needs to be used to clamp the coupling and limit it. In order to keep the coupling clamped tightly, the clamping force is relatively large, and the claws are easily deformed and there are safety hazards such as being smashed or squeezed during the disassembly process. At the same time, the assembly tightness between some couplings and the pump shaft is high, and the coupling cannot be removed by simply applying force. Utility Model Content

[0005] In view of the above problems, a mobile disassembly tool is provided, which solves the problem of damage to disassembly parts during coupling disassembly or separation from the pump shaft and falling off and injuring workers through flange connection.

[0006] In order to solve the problems of the prior art, the utility model provides a movable disassembly tool, including a cart, the disassembly tool also includes a tool flange pre-fixed on the coupling, an abutment member passing through the tool flange and the inner hole of the coupling and abutting against the end of the pump shaft, and a linear driving member that drives the tool flange to move away from the pump shaft. The tool flange and the coupling are fixed to each other by bolts, so that the end of the screw abuts against the end of the pump shaft. Under the action of the screw transmission structure, the tool flange is controlled to slide and move correspondingly on the outside of the cart, and the tool flange drives the fixed coupling to move synchronously, so that displacement is generated between the coupling and the pump shaft and they are gradually separated. This disassembly method will not damage the disassembly structure, and the position of the coupling is stable during the disassembly process, and no person needs to hold it by hand, and it will not separate from the tool and fall off to injure the staff.

[0007] Preferably, the abutment member is a lead screw and is threadedly assembled with the linear drive member, and a rotating drive member for driving the rotation is installed on the lead screw.

[0008] Preferably, the rotary drive member is a hand wheel rotatably mounted on the trolley.

[0009] Preferably, a driven bevel gear is installed on the lead screw, and the driven bevel gear is meshed with a driving bevel gear, and the driving bevel gear is rotatably installed on the trolley and its axis is perpendicular to the axis of the lead screw.

[0010] Preferably, a generator is installed on the cart, and a baking gun is movably connected to the generator.

[0011] Preferably, a steering ball is installed on the roasting gun, a collar is fixedly mounted on the trolley, the steering ball is rotatably engaged in the collar, and the roasting gun is connected to the generator through a hose.

[0012] Preferably, a dividing groove is formed around the collar, a slider is slidably mounted in the dividing groove, and the slider is fixedly mounted to the steering ball.

[0013] Preferably, a receiving groove is formed at one end of the collar away from the dividing groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model fixes the tooling flange and the coupling to each other by bolts, so that the end of the screw abuts against the end of the pump shaft. Under the action of the screw transmission structure, the tooling flange is controlled to slide and move correspondingly on the outside of the cart, and the tooling flange drives the fixed coupling to move synchronously, so that the coupling and the pump shaft are displaced and gradually separated. This disassembly method will not damage the disassembly structure, and the position of the coupling is stable during the disassembly process, and no person needs to hold it by hand, and it will not separate from the tooling and fall off to injure the staff.

[0016] 2. The utility model is provided with a baking gun structure, and the corresponding position of the baking gun is adjusted by rotating the steering ball and the sleeve ring, and the corresponding angle of the baking gun is oriented by selecting a suitable indexing groove, so that the baking gun is correspondingly arranged on the outside of the coupling. When disassembling the coupling, the coupling is evenly heated by the baking gun to loosen the assembly between the linkage and the pump shaft, thereby assisting the disassembly of the coupling.

[0017] 3. The utility model is provided with a storage structure for the grilling gun. When the grilling gun is not in use, the control slider is slidably engaged in the storage slot. At this time, the grilling gun corresponds to the top of the cart to prevent the grilling gun from extending out of the cart and being damaged by collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 7 As shown, a movable disassembly tooling includes a tooling flange 2 pre-fixed on the coupling 4, an abutment member 3 passing through the tooling flange 2 and the inner hole of the coupling 4 and abutting against the end of the pump shaft 41, and a linear driving member 21 driving the tooling flange 2 to move away from the pump shaft 41. The tooling flange 2 can be a workpiece of various structures, and the holes opened inside the workpiece can be fixed to the coupling 4 by bolts.

[0033] After fixing the tooling flange 2 to the outside of the coupling 4 by bolts, control the abutment 3 to abut the side of the pump shaft 41, and provide driving force through the abutment 3 to control the tooling flange 2 to slide and move in the direction of the cart 1 along the side of the cart 1. Move the coupling 4 through the tooling flange 2, and the coupling 4 and the pump shaft 41 are subjected to opposite forces, so that the coupling 4 and the pump shaft 41 are separated from each other.

[0034] The abutment member 3 is a lead screw and is threadedly assembled with the linear drive member 21. A rotary drive member 25 for driving rotation is installed on the lead screw. The rotary drive member 25 can control the rotation of the lead screw in a variety of power modes.

[0035] The staff controls the driving bevel gear 23 to rotate through the handle 25, and the side of the driving bevel gear 23 is meshed with the side of the driven bevel gear 24. Under the action of the meshing transmission, the driven bevel gear 24 and the abutment 3 rotate. Under the action of the thread transmission force, the linear driving member 21 with the external thread sleeve of the abutment 3 slides in the sliding hole 22 on the trolley 1. The linear driving member 21 is fixedly assembled with the tooling flange 2 to drive the tooling flange 2 to move synchronously, thereby providing a horizontal force for the tooling flange 2 to drive the tooling flange 2 to move.

[0036] The rotary drive member 25 is a hand wheel rotatably mounted on the cart 1 .

[0037] A driven bevel gear 24 is installed on the screw, and the driven bevel gear 24 is meshed with a driving bevel gear 23. The driving bevel gear 23 is rotatably installed on the trolley 1 and its axis is perpendicular to the axis of the screw. The rotating drive member 25 can be installed on the trolley 1 at multiple angles. By being vertically rotatably installed on the trolley 1, it is more convenient for the staff to rotate and apply force.

[0038] Before disassembling the coupling 4, the disassembly position of the coupling 4 is first defined, the tooling flange 2 is fitted to the side position of the coupling 4, and the tooling flange 2 and the coupling 4 are fixed to each other by bolts, so that the coupling 4 can move synchronously with the tooling flange 2 during disassembly. This fixed disassembly method makes the connection between the coupling 4 and the disassembly tooling stable. In the process of separating the coupling 4 and the pump shaft 41, a large force needs to be provided, and the disassembly tooling will be subjected to a certain reaction force. The conventional combination of the clamp and the coupling 4 is easy to be subjected to force under the action of the reaction force. The coupling 4 is easily bent and deformed, and the gripping position between the clamp and the coupling 4 is prone to relative movement, which causes scratches on the surface of the coupling 4. In the process of disassembly, the coupling 4 and the clamp are loose and fall off, which can easily injure the staff who support the workpiece. The tooling flange 2 is assembled with the coupling 4, and the movement of the coupling 4 is controlled to separate from the pump shaft 41, which can avoid the above problems. The tooling flange 2 limits the coupling 4 to be relatively stable, and does not require the staff to support it with their hands. The surface of the coupling 4 is not easily damaged during the disassembly process, and the tooling flange 2 itself will not bend.

[0039] A generator 5 is installed on the cart 1 , and a baking gun 51 is movably connected to the generator 5 .

[0040] The generator 5 can control the baking gun 51 to emit flames, and the flames act on the surface of the coupling 4 to be disassembled. When the coupling 4 is heated, it is easier to separate from the pump shaft 41, thereby reducing the resistance of the staff when turning the driving handle 25.

[0041] A steering ball 52 is installed on the roasting gun 51, and a ring 53 is fixedly assembled on the cart 1. The steering ball 52 is rotatably embedded in the ring 53. The roasting gun 51 is connected to the generator 5 through a hose 54. The lower part of the roasting gun 51 is connected to the generator 5 through the hose 54, so that the steering ball 52 is embedded in the ring 53 and rotates to adjust the direction of the roasting gun 51.

[0042] Before separating the coupling 4, first adjust the corresponding position of the roasting gun 51, control the steering ball 52 to rotate in the ring 53, and the steering ball 52 drives the upper roasting gun 51 to rotate synchronously, so that the roasting gun 51 corresponds to the side of the coupling 4, so that the flame generated by the roasting gun 51 acts on the surface of the coupling 4.

[0043] A dividing groove 55 is formed around the collar 53, in which a slider 56 is slidably mounted. The slider 56 is fixedly assembled with the steering ball 52. The dividing grooves 55 are formed around one side of the collar 53 at equal intervals, and can limit the sliding position of the slider 56, thereby supporting and limiting the steering adjustment position of the roasting gun 51.

[0044] When the steering ball 52 is controlled to be engaged in the ring 53 and rotate, the control slider 56 slides into the corresponding indexing groove 55. The slider 56 is engaged in the indexing groove 55, and the corresponding position of the roasting gun 51 can be limited. There is no need to manually support the roasting gun 51 for operation, and the roasting gun 51 is combined with the tooling, which is more convenient to use and store. In addition, multiple groups of indexing grooves 55 are opened on the front side of the ring 53. The slider 56 is engaged in different indexing grooves 55, and the roasting gun 51 can be limited in different directions, so that the corresponding position of the roasting gun 51 can be adjusted according to the size of the coupling 4, and the operation is convenient.

[0045] A receiving groove 57 is formed at one end of the collar 53 away from the indexing groove 55 .

[0046] When the roasting gun 51 is not in use, the steering ball 52 is controlled to be engaged in the ring 53 and rotated, and the roasting gun 51 is rotated to the top of the cart 1, so that the slider 56 is engaged in the storage groove 57 opened on the other side of the ring 53. The position of the roasting gun 51 is quickly limited by the engaging structure of the slider 56, so that the roasting gun 51 is stored above the cart 1, so as to avoid the roasting gun 51 being unfolded to the outside of the cart 1 and being damaged by collision with other workpieces during the use or storage of the workpiece.

[0047] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
